The heat you feel from boiling water is primarily convective heat, which is heat carried by the physical movement of the water molecules. In addition, there may also be some radiant heat from the steam rising off the boiling water.
Iceberg.Heat is anything above absolute zero (-273 degrees C).It is the total energy of molecular motion in a substance while temperature is a measure of the average energy of molecular motion in a substance. Heat energy depends on the speed of the particles, the number of particles (the size or mass), and the type of particles in an object. Temperature does not depend on the size or type of object. For example, the temperature of a small cup of water might be the same as the temperature of a large tub of water, but the tub of water has more heat because it has more water and thus more total thermal energy.The iceberg is a huge object with a lot of mass or volume than a pot of water.Therefore due to the massive size of the iceberg the amount of heat (even though it is not as 'hot' as the boiling water) is greater.
I was unable to find any information on a "IGEma". If this is a type of a boiling water kettle, you will see the orange indicator light up on the side of the pot when water reaches boiling.
A long-handled spoon is better for stirring boiling water as it allows you to keep your hand at a safe distance from the heat. Additionally, a heat-resistant material like stainless steel or silicone is recommended to prevent the spoon from melting or warping in the hot water.
Two types of evaporation are solar evaporation, which occurs when water is heated by the sun, and mechanical evaporation, which involves the use of machines to heat water and accelerate the evaporation process.
A student would need a thermometer to measure the boiling temperature of the two types of water and a scale to measure the quantity of salt added. They would also need a source of heat to boil the water and control variables such as the volume of water and the type of container used.
convection
No, boiling water in a kettle on a stove is an example of conduction - the heat from the stove directly transfers to the kettle, heating the water inside.
The type of energy which is used to boil water is commonly heat energy. This will result to a changes from the liquid state to gaseous in form of water vapor,.
Boiling water involves heat transfer through convection and conduction. Convection occurs as heated water rises, carrying heat throughout the pot. Conduction transfers heat from the heat source to the water at the bottom of the pot.
Boiling water undergoes a physical change from liquid to gas as it reaches its boiling point and evaporates into steam. The heat energy supplied causes the water molecules to move faster and eventually break free from the liquid state.
Polypropylene (PP) and polyethylene (PE) plastics are generally considered safe for boiling water as they have high heat resistance and are less likely to leach harmful chemicals into the water. It is important to check the specific type of plastic and ensure it is labeled as microwave-safe or heat-resistant before using it to boil water.
This type of heat transfer is called conduction. The transfer is from the warm hand to cool water.
Copper transfers the greatest percentage of heat to the contents of the pot (water). As for the shape of the pot ..... lower and about 1" wider on all sides than the heat source.as wide as the heat source.
A heat-resistant borosilicate glass beaker or a stainless steel pot would be most appropriate for making a boiling water bath. Avoid using regular glass containers as they may not be able to withstand the high heat and might shatter.
The heat transfer in this scenario is primarily through conduction, where heat is transferred from the pot to the water through direct contact. As the water at the bottom of the pot absorbs heat, it becomes less dense and starts to rise, leading to a process of convection where the warmer water moves upward and the cooler water moves downward.

Objects made of materials with high melting points, such as stainless steel, glass, or ceramic, can hold boiling water without melting. It's important to check the specific material's heat resistance before using it with boiling water.
